Alexander A. Klimov 6b5106ffdd IcingaDB#Stop(): don't block shutdown, timeout instead 2022-03-02 16:39:44 +01:00

Alexander A. Klimov 8ea62f7fc7 Icinga DB: keep history in memory until written to Redis 
by putting the messages into a Bulker and retrying each chunk.

Julian Brost 6007848146 IcingaDB: export environment_id via API 
Primarily required for Icinga DB integration tests at the moment, but could
also be helpful in other situations.

Julian Brost 4ade4c757b IcingaDB: write new environment to icinga:stats stream 2021-11-05 14:14:37 +01:00
Julian Brost 525dd50859 IcingaDB: introduce a new environment ID derived from the CA public key 
In order to avoid changes to the environment ID, it is now no longer derived
from the Environment constant but instead from the public key of the CA
certificate. This ensures that it is different between clusters by default, so
no additional changes have to be done to allow two clusters to use Icinga DB to
write into the same database.

To prevent the ID from changing when the CA certificate is replaced, it is also
persisted into the file /var/lib/icinga2/icingadb.env, so if that file exists,
it takes precedence over the CA certificate.

Julian Brost 929ebd0f6c IcingaDB: start initial sync after all child connections are established 
Icinga started the initial config sync right after the first Redis connection
was established. If any other connections would take longer to connect than
when it's first needed, queries were discarded.

Julian Brost a50120c399 IcingaDB: start parent connection after children are initialized 
The loop in the connected callback of the parent connection uses m_Rcons which
previously was only initialized after that connection was already started.

Alexander A. Klimov ae9b371128 Icinga DB: priorize state > config 
I.e. do the following in parallel (highest priority first):

* Stream state changes to icinga:runtime:state
* Sync config and initial state,
  then let queued runtime updates to the just synced state pass

Julian Brost a5dc52dea5 IcingaDB: use XADD MAXLEN instead of custom Lua script for heartbeats 
The existing Lua script adds a new entry to a stream and then deletes all older
entries. The same can be achieved by using `XADD ... MAXLEN 1`.

Julian Brost 2d080f14eb IcingaDB: start initial dump in callback instead of timer 
Previously, the initial config dump was started in a timer executed
every 15 seconds. During the first execution of the timer, the Redis
connection is typically not established yet. Therefore, this delayed the
initial sync by up to 15 seconds.

This commit instead triggers the sync from a callback that is executed
after the connection is successfully established.

The timer is removed completely. On first glance, it looks like it would
ensure that a lost connection is reestablished, but this is handled
internally by RedisConnection. After the config has been dumped once,
that timer wouldn't ever attempt a reconnect anyways.
